This invention relates to Sprayers. It isamong the objects of the present invention to provide a convertible sprayer which maybe utilized as a gravity feed or forcefeed device.

A further object of the present invention is to provide a novel and improved sprayer in which trigger means are provided for jointly operating a lurality of valves to control a flow of fluid r'om the sprayer.

A further object of the present invention is to provide a convertible sprayer adapted for use in conjunction with an external sup ply of air andpressure.

means for controlling the configuration ofthe projected stream of sprayed material.

Other objects of thepresent invention in-. clude the combination and interrelation of parts, whereby the whole forms a simple efiicient convertible structure readily designed to meet the demands of economic manufac-f ture. 8 Numerous other objects and advantages of the present invention-will be apparent from a considerationof the following speei-" accomtaken on lines l Fig. 6 is afront'elevation of the spraying nozzle.

Referring more particularly to the drawings, the device preferably includes a handle able configuration to provide ready gripping means. The upper end of the handletorms a tubular yoke 11, through which an apertured nozzle barrel 12 extends. The yoke 11 is apertured as at 13 and internally threaded Another ob'ect of the invention includes the provision of a novel adjustable nozzle is normally urged forwardlyfby" sion of a 10, which is hollow as illustrated and of suitwhen "the device is used as a force feed NT OFFER. .1

for thereception of a pressure supply tube 14, which extends through the handle for association with a suitablesupply tube'15, as

illustrated. t j

To rovidefor the conversion ofthe device from orce feed to gravity feed, or vice versa', 1

"the barrel 12 is rotatably positioned within the yoke llandis provided with an extend ing flange 16 adapted to abutthe forward face of the yoke 11. Thereargend of the barrel 12 isinternally threaded asat 17, for the 6 reception of a securing plug 18, which is provided with an extending flange 19, which through themedium of the threads 17 en-; gages a suitablepacking 20, and incombina tion with the flange 16, retains thejbarrel against rotatio n. The plug 18 isfcentrally I apertured for the reception therethroughof ayalve-controlled rod 21. The plug 18 is provided with a suitablepacking gland 22 -which prevents leakage around the rod 21 k as it passes through the plug 18.

For actuating thevalve rod 21,'a trigger i i 23 is provided, its upper'end being bifurcated to pass around the yoke 11, the extremities of the furcations being pivoted as at 24 to the yoke. Intermediatethe ends of the furcations, at substantially: Ushaped actuating suita member 25 isprovided joined to the yoke as i willbe seen that the trigger is also normally 'urgedforwardly through the medium of the member 25 and its association as at 26 with the furcations of the trigger. It will also be the member 25 rearwardly and thus moves,

rearwardly the valve operating rod 21against the tension of the expansion spring 28.

Referring more particularly to Fig. 1',

sprayer,a spray materialreceptacle 3O isprovided suspended from the barrel 12 by en gagement thereof with an internally threaded flange 31 mounted upon the barrel 12, a

i seen that pressure upon the trigger moves suitable washer 32 being provided between the receptacle 30 and the barrel 12. Associated with the flange 31 a valve member 33 is provided, within which a valve seat nipple 34 is secured, against which a mushroom valve 35 is ada ted to seat, the valve being normally close through the medium of a contractile .spring 36, which surrounds a valve stem 37, which projects within the barrel 12 for actuation by a conical actuating member 38 mounted intermediate the ends of the operating rod 21. The conical member 38 is a preferably hollow and internally threaded as indicated, thus providin for separation of the ends of the rod 21 an for providing adjustment of the length of the rod, whereby the actuation of the plunger 37 by the member 38 maybe controlled and also to effect adjustment of the extremity thereof with respect to the aperture in the member 45.

For directin the required amount of compressed air to t e receptacle 30 and for intermediately supportin the operating rod 21, a member 40 is provided within the arrel 12, and as shown in Fig. 5, is spaced from the sides of the barrel 12 to permit the passage of the compressed air therearound. Packing 41 is provided adjacent the aperture in the member 40, throu h which the rod 21 passes, the packing 41 eing secured in position through a threaded retaining member 42 against which the rear flat face of the operating member 38 abuts, thus restricting the forward movement of the valve rod 21 under the influence of the s ring 28.

, For directing the uid to be sprayed to the nozzle, the member 40 has an an ularly characterized bore 43, one end of w ich extends through the side of the member 40 for association with an internally threaded nipplereceiving projection 44 of the barrel 12. The other end of the bore 43 extends axially of the barrel 12, its forward end tapering for association with a tapered discharge member 45, within which the forward end of the rod 21 is received and movable for closing the end thereof. This movement of the trigger simultaneously controls the valve 35 and the dischar e of fluid through the bore 43. When the evice is utilized in the osi tion shown in Fi 1, a nipple 46 is provided, which extends we lwithin and a proximately to the bottom of the receptac e 30, and is surrounded by a strainer 47, which is secured to the nipple by member 48, which is receivable within the nipple and expands to retain the strainer 47 int e position as illustrated.

Referrin more particularly to Fi 6, the forward en of the barrel 12 is provicfed with an im roved nozzle, the barrel 12 being flange as at 50, and having received in the extremity thereof, an internal stationary nozzle member 51', which is provided with a pluthe provision of a spring rality of apertures, shown by the dotted lines in Fig. 6 and indicated at 52, which preferably include one central aperture which receives the pointed extremity of the member 45, and a pair of horizontal and vertically arran 'ed apertures on either side thereof. Associated with the flange 50, an outer nozzle member 53 is provided, adapted for rotation with respect to the barrel 12 and which includes the apertures 54, one of which at all times remains in registration with the center aperture 52, while the outer two may, by rotation of the member 53, be arranged for coincidence with either the vertical or horizontal apertures 52. Thus by rotation of the member 53, whereby the apertures-54 aline with the vertical apertures 52, a vertical fan-shaped spra results. A similar horizontal s ray resu ts through the association of the orizontal a ertures 52 with the apertures 54, and by the a inement only of the central aperture 54 with the central aperture 52, the usual conical discharge of spray is rovided for.

Referring more particular y to Fi 3, it will be seen that by loosening of the p ug 18, the barrel 12 and its associated parts may be revolved with respect to the handle 10, and the device may assume the position as shown in .said figure for gravity feed of the sprayed material. and short valve stem 37 are replaced y the long nipple 55 shown in Fig. 3, and the long In such case, the short niplple 34v valve and valve stem indicated at 56. Thus air under pressure admitted to the handle is directed to the top of the receptacle 30 for exerting pressure to discharge the fluid from the receptacle. In this use of the device, the long nipple 46' is also done away with and a short mp le 57 is provided with which the strainer 47 is associated. It will be readily seen that the operation of the device is eflicient in either position and that the change from one position to the other may be readily accomplished by interchange of the nipple 46 and bushing 34 and the provision of the valve assembly 56.

From the foregoing it will be readily seen that the present invention provides a novel and improved convertible pressure spray means which is simple and eflicient in operation and which carries out the objects of the invention as herein set forth in a novel, approved and eflicient manner.
